what is chain grate biomass boiler for sale the republic of belarus

Grate firing has been the most commonly used firing method for combusting solid fuels in small and medium-sized furnaces since the beginning of the industrialization. Coal, waste and biomass fuels are usually burned in grate boiler. In the chain boiler, the coal is moved backward from the front of the grate, and the air from the bottom up to the furnace, and as the furnace is constantly moving backwards, the fire, combustion, burning and other stages occur in sequence. Traveling or chain grate stokers feed coal out onto a rotating metal belt that supports the fire. Solid fuel is fed from a hopper. Grate speed is automatically controlled to maintain desired steam pressure. Burning progresses as the belt moves from front to back of furnace. Combustion is essentially complete at the back end of belt, and ash is dumped off into an ash pit there.

Industrial biomass boiler for sale the republic of belaruss is a major driving force for social development, but also brought great pressure on the environment. Whether coal-fired boilers, biomass boilers, or, when the supply of energy, the emission of pollutants will soot and nitrogen oxides. Some enterprises in order to save costs, the pursuit of more profits, but also allowed to change the fuel, biomass boilers burning coal steal, wood, and even garbage doping or other industrial waste, produce dioxins and other carcinogens directly into the atmosphere after combustion, pushing PM2.5 concentrations.

Since started Blue Sky Battle horn Guangdong Province, many cities have begun to respond positively, Dongguan City, is one of them. Atmospheric do in-depth business thoroughly, and the development of industrial boilers business accounting, confirming the city's need to eliminate highly polluting boilers have 765 units, of which 728 sets of biomass boilers, 37 coal-fired boilers. Subsequently, promote the transformation of facilities operations out of high pollution boilers within the city.

As of May 14, 2019, the city's 324 enterprises active removal of 363 coal-fired boilers burning biomass, as well as 83 to 84 companies demolition of the old boiler pipes, 447 completed phase-out plan of the boiler in advance.

Although there are many companies take the initiative to carry the main responsibility for the ecological environment, but there are still some chances enterprise.

Atmospheric Office official admitted that "in the daily inspection, the company found that some still illegal use of boilers, perfunctory 'coal to gas' work." Among them, although some enterprises written off coal, biomass fired boilers, but because of natural gas boiler installation behind schedule, forced production needs, but to let the old boiler continues posts. There are companies more "capricious", install two-way pipeline for new and old boilers, strict supervision when using gas-fired, law enforcement officers continue to take a coal burning biomass. There are even companies deliberately delayed "from coal to gas," progress, choose to enable the original write-off of the boiler.

This year, the Office of Atmospheric inspection personnel to go to 244 companies in the field to check the boiler usage, found that 42 enterprises there is illegal use of boiler problems. Among them, there are 18 companies of illegal use of biomass boilers has been canceled. "Not only pollute the atmosphere, there are still significant safety risks." Atmospheric Office inspection personnel Lurui Quan said, "the city's coal-fired, burning biomass boilers as well as 113 units, involving 94 companies, is expected to complete phase-out year, access to clean energy. "simple behind the data, there is a thick ledger out of the transformation of the boiler," when removed, when write-off, out of a pin number one glance. "

Atmospheric Office official also said the recent city towns Street (Park) Atmospheric Office will carry out investigation and remediation special action has been canceled boiler, supervise and guide enterprises to demolish the old boilers and pipes, put an end to "note not sell" phenomenon. At the same time, urge enterprises will have been dismantled boiler dedicated to the sale of scrap recycling company, effective way to solve the old boiler, complete eradication of pollution and safety hazards.

Boiler efficiency calculation formula

Definition of Boiler Efficiency is “The percentage of the total absorption heating value of outlet steam in the total supply heating value.” In other word, it is a rate how the boiler runs efficiently. The thermal efficiency of our coal-fired boilers is 84~92%, the efficiency of fuel and gas boilers is 96~99%, and the efficiency of biomass boilers is 86-93%. The higher the efficiency of the boiler, the better the heat transfer performance. Increasing boiler thermal efficiency can reduce boiler fuel consumption and reduce boiler operating costs. Increasing the thermal efficiency of the boiler is to increase the effective use of heat and reduce the heat loss of the boiler. The key point is to reduce the heat loss of the boiler exhaust gas and the loss of mechanical incomplete combustion.

Fuel flexibility characteristic for CFB biomass boiler for sale the republic of belaruss plays an important rule in industrial and utility size applications.Possibility to use wider range of fuels that has been long time considered as by-products or wastes and possibility to design boilers able to operate with alternative fuels is an important factor that improves fuel delivery security and plant economy.Presented article is based on similar publications that present Foster Wheeler's experience in design and delivery of the CFB boilers for wide range of coals and cofiring by-products of crude oil refining and coal processing. Aspects of biomass cofiring will be also presented.
